Speoication of Letters Patent.' Patented Sept. 20, 1910. Application iled February 25, 1910. Serial No. 545,863.

' Tofcilt wlwm, 'it ma/y concern:

Beit known that I1, GUs'r CA-RisoN, a citizen of the United States, residing at Jamesl towu,in the county of Chautauqua, State of New York,y have invented certain new and luseful Im rovements in Metal- Doors; and

V I do here y declare the following .to be a A vention, such aswilfl enable others skilled in I1o y usethe same.

`full', clear, and' exact description of the intheuart to which it appertains to make and 'Ehe inventiony relates to a door and more rripa/iftlicularly to the class of' metallic doors.

. l The primary object of the invention is thc'provision of a door in which tlie'frame fthe-reef is entirely constructed of metal so minimum expense.

Withtliese and other objects in View, the invention consists .1n the construction, combination, and arrangement of parts, as will be-hereinafter more fully described in det-ail, illustrated in the accomanying drawings, which disclose the pre erred form of .embodiment of the invention, to enable those skilled in the art to practice the invent-ion,

andas pointed out in the claims hereunto appended.

In the drawings :l `igure 1 is a frontclevation of a metallic door constructed iii accordance with the invention. Fig. 2 is a transverse sectional view on the line 2-0 of Fig. 1. Fig. 3 is an enlarged fragmentary sectional view taken on the line 3--3 of Fig. 1. f Fig. 4 vis a fragmentary sectional view of a modification.

" Similar reference characters indicate corresponding parts throughout. the several views in the drawings.

Referring to the drawings by numerals, 8 designates generally a metallic door formed with a hollow frame structure comprising Stiles 9 and 10, the latter being integral `with transverse top and bottom rails l1 and 12, while the stile 9, is connected to the said top and bottom rails in n, manner as will be hereinafter more fully described.

The stiles and atop and bottom rails are constructed of sheet I netal material bent to form side faces 13, and an edge face 14, the latter being the desired thickness of the door. The inner edges of the Stiles 9 and 10, and the tos and bottom rails 11 and 12, are bent inwar 1y towardi each other to formV a, right angular flange 15, the same being also pro- -vided with an inbent portion. forming a locking tongue 16, disposed in s aced parallel relation to the side faces 13, o the Stiles and to and bottom rails. Disposed between the si e faces 13, adjacent the flange 15, formed. at the inner edges ofthestiles and top and bottom rails are channeled plates 17, the free edges of which are bent inwardly as at 18, so that these bent yportions will abut or lie conti nous to the flanges 15, between the side aces 13, andf the tongues 16, thereby closing the inner edges. of the stiles and top and bottom rails. XIt is to be noted however, that these flanges 15, and tongues 16, extend longitudinally of 4the stile 10, only for the distance between the inner edges of the top and bottom rails 11 and 12, for the purpose as will be-hereinafter more fully described. l

Disposed against the exterior surfaces of the flanges 15V are opposed inwardly converging curved Strips 19, each having one longitudinal edge bent inwardly to forni an abutment flange 20, the latter being disposed against the flange 15, and this Harige 20, is bent to provide a locking tongue 21, extending in the opposite direction with respect to the locking tongue 16, while the opposite longitudinal edges of the said strip 19, are bent inwardly to form locking flanges 22, engaging against opposite faces of a metallic panel 23, fitted between the strips 19, at the innler edges of the stiles and top and bottom rai s.

Engaging the lookin flanges 22, of the strips 19, are substantial y U-shaped or channeled lockingstrips 24, and also engaging the locking tongues 16 and 21, of the Stiles and top and bottom rails and strips 19, are channeled locking strips 25, whichlatter securely fasten the said panel engaging strips 19', to the Stiles 9 and 10, and top and bottoni rails 11 and 12. At the ends of the top and into practice; Also slight-changes, varia* 35.

together with the tongues 16, on the stile 9,-

above and below the points of juncture of the strips 19, with the said` stile 9, are, engaged by channeled locking strips 29, where by the said stile 9, is connected to the upper and lower rails of the door.

In Fig. 4 there is shown a slight modi'ication in the formation of the paneling engaging strips of the door frame. Mounted adjacent the inner edges of the stiles 9 and 10, and the upper and lower rails 11 and 12, are molding strips 30, the same being formed with bearing seats 31,reeeivin the edges of a glass panel 32, the latter eing held in these seats 31, by clampin strips 33,' which are detachably secured tot ie molding strips 30, by 'means of screw' members 34, by the employment of which enables the glass panel 32, tol be removed when the occasion requires. The said molding strips 30, are secured to the stiles v9 and 10, and the top and bottom rails 11 and 12, in the same manner as the panel strips 19, heretofore described.

The invention is show-n and described inI connection with the formation of a metallic door although it is to be understood'that the said invention is Inot limited to this particular construction because window sashes and other analogous structures may be made and' are contemplated in carrying the invention tions, and modifications may be made such. as

1 come pro erly within the scope of the appended aims' without departing from the i meer spirit of the invention or sacrilicing any of itsadvantages. I

1. A door comprising single sheets of material, one of the sheets bemg bent to provide a stile, top andbottom rails, the other sheet bein bent to provide a stile, the edges of the sti e sheets being inturned and bent to provide L-shaped flanges, channeled strips el'lgaging .the flanges, panel retainings'trips having flanges correspondingly shaped to the first named flanges and abutting against the latter, and channeled securing strips engaging said flanges and locking the panel retaining vstrips against the inner faces of thestiles and top and bottom rails.

2. A door comprising single .sheets ot' ma- .terial, one of the sheets being bent to provide a stile, top and bottom rails, `the other sheet being bent to provide a stile, the edges of the stile sheets being inturned and bent` to provide L-shaped flanges, channeled strips engaging the flanges, panel retaining stri s havin flanges correspondingly shaped to t e first n med anges and abutting against 'the latter,l channeled securing strips engaging said flangesmand locking the panel retaining strips against the inner faces ,of the stilesY and top and bottom rails, and U -shaped stri ssecuring the panel retaining strips toget er. l

In testimony whereof, I afiix my signature, in presence of two witnesses.` 1 GUST CARLSON.
